"Excellent improvement to the original Gilson Microman; particularly in user comfort (fits more easily in the hand, better suited to extended use). The new volume lock is also very good, stops any drift while in use."

Vacuum for freeze-drying
The RC 6 pump is a combination of a two-stage rotary vane pump and a two-stage chemistry diaphragm pump for optimized corrosion resistance. The diaphragm pump maintains the oil reservoir under vacuum in order to keep the partial pressures of solvent vapors at levels below their condensation points and to reduce largely the concentration of oxygen and corrosive gases. Performance features:
reduced internal corrosion, even when working with corrosive vapors
oil changes typically reduced 90% or more compared with rotary vane pumps alone
excellent environmental friendliness due to efficient solvent recovery (accessory kit PC 8 with emission condenser; or as pumping unit PC 8)
drastically reduced amount of waste oil for disposal due to extended service inter...Read more
